','To all 'whom it muy concern.:

Be it known that we, RICHARD NETT and HENRY H. VAUGHAN, citizens of BUR- "forming, a part of thisspecification.

Our invention relates -'to sills for railway cars, including .tliose generally known as center-sills and draft-sills.'-

prz'ictic'alg -operation of railroads, liasf'hei'etofore been experienced old center-sills and draft-sills,

rasfforexainple, 'wooden sills tosills of metal .construction in cais at inconvenient-,dis-

tances from railroad equipment construction and repair shops. Difficulty has also been l, in 'cases where, under excessive shocks to the suffered injury on account of a failure to .car body, the car body, or parts thereof', has

employ the resiliency of the car body to assist in the absorption of said heavy shocks oiblow`s.- l v The object ofv our invention is to meet -l-these diiiculties by providing a metal construction especially adapted to'coiiveniently replace old wood sills and 'adapted to employ the resilience of the car body. itself in the @absorption of excessive' shocks and blows `.fl;.transmi-tted to it through the 'draft members providing a unitary metal structure 'that 4fmay-in assembled condition, be shipped to 'WVe accomplish these objects by of the car.

points distant. from car shops and conveniently and readily applied, and employed to reconstruct the car body by using the same In this strucl struction-and so attached to ythe center-sills .and the body-holsters of the car as to make v i received; by the draft members of the car in the direction of the stress of excessive blows i operationwhentransmitted to the car body eccentric thereto.v

. T In our construction we employ ap'a'ir :of center-sills each comprising a Z-bar and ex-A f tending longitudinally from 4end to end oi the car body and above the body-,bolster and securedt-o the said center-sills` in front of l @the body-.holsters at eitlier end, a pair'of draft-sills that extend below the center-'sills and are constructed to receive the draft rigging' between them, which draft-'sills are provided wit'h reinforcing angle irons eX- tending longitudinally thereof and are also provided with an oblique flange extending from the bottoni of the draft-'sills length to the center-sills.

In replacing wooden .center-sills with .our construction,'it is necessary Only I,todiseiigage the old center-sills and bolstersand insert the assembled center-sills and'draft-sills and if desirable, new bolsterssecui'ed to the saine, and suitably secure said structure'to the car frame. The use of the Z-bar centersills passing over the body-bolster `enablesus 'to secure a strong .constructionat the point of union of holsters and center-sills, and the draft-sills, by being extendedy rearwardly of thc bolster, are by reason thereof capable of distributing shocks alonga wide area of the. center-sills. The durability andeliiciciicy'of the draft-sills in service is insured vby the em loymentl of the angle irons, two

for each raft-sill, one 'ofwhich directly abuts the body-bolster:

In our construction, the draft. rigging is in excess of the resilient capacity of the draft rigging are absorbed-by .being eccentrically applied to our unitary structure, through t-hedraftsills and oblique flanges thereon. The resiliency of the car body is employed 'to absorb 4and case the f heavy shocks of service by applying them;eccen trically through this construction and wit-hout resulting in damage Ato the samef In the drawings, forming apartyozf this specification,-Figure 1. isa'side elevation partly in longitudinal section online 1.1 ot Fig. 3 of draft-sills for railway.,cars enilbodying our invention; Fig. 2J isafcrosssection on line V2 2 of-Fig. `1.

Fig. 5 is `an elevation of the draft and center-sills of a car underframe -(broken away in central portion) in ver-ticaldongi- 'tudinalsection on line 5-5 of-F-ig. 6; Fig.

6 is a plan view of the draftand center-sills 'iio of acarA underframe (broken away in th'e central portion thereof) partly in horizontal longitudinal section on line 6 6 of Fig. 5 l

` ".directionpreferably outwardly. By'reason of'this Z ar form of center sill .we -are not only enabled to employ the car-bodys resiliency to absorb and ease heavy shocks, as

hereinafter mentioned, through the-tendency ofthe sills to give in a slightly bowing action along their length, but we utilize the lateral Vresiliency o f the Z-bar arising through the-distribution of the weight of the remainder of the, 'car' body upon 'this particular type of center sills to ease and absorb heavy shocks. This eiiicient lateral resiliency .cannot be obtained in any other Yform of center sil-l, Ias lfor instance channel beams. in which both flange's' are on the same side of the connecting web.

Referring to the drawings, 7-7 represents 'the body-holsters of a railway car, 88 the vcenter-sills and 9-9 the end-sills .of the same. The center-sills are of metal, preferably rolled steel Z-bars, though rolled steel plate-bars pressed into Z-shape maybe l employed, extending from the end-sill at one end to the end-sill at .the other'end of :the car underfranie and above the, bodybolstersto which they are suitably secured. The end sheathing 10 of the car is secured' at its lower ends between. the end-sills and the buffer-.block 11, along the length. of theA same, whichbuler block-bears the striking-- plate 12. Dependent 'from each center-sill;v

" and secured to the inner face thereof by 'end -of the'car underframe.

-the riyets'13-13' is a draftfsill 14, a pair oppositely faced being provided at either Each draftA -sill is of greater vertical' lwidth Athan the center-sill to whichit is attached, and'comprises 'a metal plate 'o f suitable thickness', provided at its'forward end with .an inwardly turnedflange'l adapted to engage .theend-sill angle iron 16. Suitablysecnred to. the inner face of each draft-sill, prefer. ably by' rivets, is a stop-member'N, the said- 60' stop-metnbers being oppositely 'arrangednear either end of, the c ar underfra-me.- '1 he` other pirtsof the draftriggin are mount--V ed 'herein and while' any suitab e kindV may befemployed, we have shownin the draw;

The tie-plate 24 supports the parts within the yoke and the 'draw-bar carry-iron 2 5 supports the draw- Infront vof the body-bolster the 'draft-sills A dimensions than the adjoining center-sills and preferably back of the stop-members, each draft-sillv along its lower edge is formed' obliquely to the longitudinal plane of the center-sills and said oblique portion extending rearwardly From the front edge 27 I of the bodybolster, each draft-sill extends rearwardly back of the body-bolster and along this portion of its length is substantially of thesame vertical dimension as the web 28 of the ad.; jacent Z-bar center-sill to 'which it is riveted. Along the aforesaid oblique portion of the lower edge of each draft-sill and extending rearwardly to the end of the same is provided an inwardly turned flange 29 of strong construction; a, reinforcingangle.

iron 30 extendsforwardly from said flange 29 along the lower, outer length of the draft-s illadjacent thereto and is riveted to said draft-sill. Between this angle iron and :as far as the plane of the upper surface 26 vof the bodybolsterthe adjacent portion of the center-sill and engaging therewith iand riveted to the lower flange thereof is provided' a further angle iron 31, extending from the forward end of vthe draft-sill to andabutting the front edge .27 of thebodybolsten S last-mentioned anlgle iron is .also riveted to the draft-sill.
